Fig 1.
Diagram of the vertical zones of host trees where epiphyte is distributed.
TZ, ICZ, MCZ and OCZ indicated trunk zones, inner crown zones, middle crown zones and outer crown zones of host trees, respectively. This disgram is redrawn from Johansson (1974).
Fig 2.
Abundance (A) and species richness (B) of vascular epiphyte at the different crown zones upon host trees. Different letters above boxes indicated significant difference for alpha = 0.05. TZ, ICZ, MCZ and OCZ indicated trunk zones, inner crown zones, middle crown zones and outer crown zones of host trees, respectively.
Fig 3.
Abundance (A) and species richness (B) of vascular epiphytes at the five orientations upon host trees. Different letters above boxes indicated significant difference for alpha = 0.05. A, E, S, W and N indicated the five orientations of all directions, east, south, west and north where epiphytes grew upon host trees, respectively.
Fig 4.
Relationship between the vascular epiphyte species richness and host tree diameter (DBH) across all six study species (Engelhardtia roxburghiana, Ternstroemia gymnanthera, Syzygium buxifolium, Illicium ternstroemioides, Distylium racemosum and Cyclobalanopsis disciformis), using a regression of breakpoints based on generalized linear model.
Different symbols showed different host species. The lines represented locally weighted means and the shaded area represented 95% confidence interval.
